We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structure which is fabricated out of porous ...
[EN] A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An efficient collimation of the beam behind ...

[EN] From the acoustical point of view one of the most extreme events is the lift-off of a rocket. In such events, an enormous amount of energy is liberated in the form of acoustic waves that are reflected in the launch ...
Herrero-Durá, Iván; Cebrecos, Alejandro; Picó Vila, Rubén; Romero-García, Vicente; García-Raffi, L. M.; Sánchez Morcillo, Víctor José(MDPI AG, 2020-03)
[EN] We report a theoretical and experimental study of an array of Helmholtz resonators optimized to achieve both efficient sound absorption and diffusion. The analysis starts with a simplified 1D model where the plane ...
We consider the problem of parametric sound generation in an acoustic interferometer
containing a fluid. We have taken explicitly into account both the influence of the nonlinearly
generated second harmonic and the ...
[EN] The finite-element time-domain method for elastic band-structure calculations is presented in this paper. The method is based on discretizing the appropriate equations of motion by finite elements, applying Bloch ...
